The Evansville Police Department says Stephanie Cruce stabbed her husband, Benjamin Cruce, with a knife several times.
That happened in their home in the 3000 block of Crossbow Lane just after three o'clock Tuesday morning.
Officers say Cruce told them her husband was very drunk and harassing her and she wanted to defend herself.
Cruce also admitted to hitting her husband in the back of the head with a baseball bat.
Police say Benjamin Cruce never physically assaulted his wife and that the entire incident happened in front of the couple's 11-year-old son.
Benjamin Cruce was taken to a local hospital for his injuries, but there is currently no word on his condition.
